ATTORNEY Patented Apr. 22, 1930 PATENT oFFicE SAMUEL J. SMYTH, 0FHAWTHORNE, CALIFORNIA CLOSURE CAP Application filed July 5, 1927. SerialNo. 203,489.

My invention relates to closure caps for containers, such as milkbottles, cheese .boxes, or any form of container where the caps areformed of paper, cardboard or other material.

It is a purpose of my invent-ion to provide a closure cap of the abovedescribed character which eliminates the employment of any instrument 1nremoving the cap from 'the container by the provision of projections anthe cap adapted to be gripped by the hand and actuated to flex the capto a released position with respect to the mouth of the container.

I will describe only one form of closure cap embodying my invention, andwill then point out the novel features thereof in claims.

In the accompanying drawings:

Fig. 1 is a view showing in edge elevation. one form of closure capembodying my in- V vention in applied position to a milk bottle.

Fig. 2 is a view showing the closure cap in top plan and in appliedposition to a milk bottle.

Fig. 3 is a vertical, sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a view similar to Fig. 3 showing the cap in released position.

Fig. 5 is a vertical, sectional view taken on the line 55 of Fig. 3.

Similar reference characters refer to similar parts in each of theseveral views.

Referring specifically to the drawings, my invention, in its presentembodiment, comprises a disk-shaped body 15 of cardboard or any othersuitable material capable of being manually flexed, and of such diametermouth so that the subsequent removal of the cap from the bottle can bereadily effected.

In practice the cap is removed from the bottle mouth by placing thethumb and finger against the outer sides of the ribs 17 and pressinguntil the edges of the cap at the sides of the ribs rise from the sidesof the bottle mouth when the cap can be removed without danger ofspilling its contents. To again seal the bottle, the cap can be replacedby pressing its edges down flat until the previous condition isattained.

A cap constructed in accordance with my invention obviously eliminatesthe use of an instrument to effect its removal from a container, and inremoving the cap it is not distorted or otherwise impaired in respect toits further use in sealing the contents of the container.

Although I have herein shown and described only one form of closure capembodyingmy invention, it is to be understood that varlous changes andmodifications may be pressed together to cause upward flexing of theedges of the body.

2. A closure cap comprising a body of flexible material adapted, when inthe mouth ofa container, to be engaged at its edges and retained inclosing position within the mouth, and spaced protuberances on the bodyfor flexing the body to cause portions of its edges to move outwardlyand thus free themselves to allow removal of the body' from the mouth.
